Struct daab::ArtifactPromise

pub struct ArtifactPromise<B: ?Sized> { /* fields omitted */ }

Encapsulates a builder as promise for its artifact from the ArtifactCache.

This struct is essentially a wrapper around Rc<B>, but it provides a Hash and Eq implementation based no the identity of the Rcs inner value.

All clones of an ArtifactPromise are considered identical.

An ArtifactPromise can be either resolved using the ArtifactCache::get() or ArtifactResolver::resolve().

Methods

impl<B: Builder + 'static> ArtifactPromise<B>

pub fn new(builder: B) -> Self

Crates a new promise for the given builder.

Trait Implementations

impl<B: ?Sized> Clone for ArtifactPromise<B>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<B: Debug + ?Sized> Debug for ArtifactPromise<B>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for ArtifactPromise<dyn Any>

impl<B: Builder + 'static> From<B> for ArtifactPromise<B>

fn from(b: B) -> Self

Performs the conversion.

impl Hash for ArtifactPromise<dyn Any>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq<ArtifactPromise<dyn Any + 'static>> for ArtifactPromise<dyn Any>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
